This
tutorial covers the subject of using the Rectangular
Marquee tool in a practical photographic sense.
The file
you will download will be zipped together with the
original image used by the author and a document
file to help you get the best from the video. Here
we demonstrate in a practical way how we may use
the rectangular Marquee tool in our Photography.
In this downloadable movie tutorial we use the tool
to isolate an area for editing, but also to protect
an area against unwanted editing. We straighten
a curved horizon in our image that was caused by
a wide angle lens and also use the Rectangular Marquee
Tool to darken or shade the top of our image.
In the original
image below you can see the horizon sloping upwards
towards the left.

In the completed image the horizon
is now perfectly straight and the sky has more impact
